The next step for one property

Sinkholes are uncommon here; watch for new depressions after heavy rain or leaking pipes.

That works out to roughly 9 of Saunders County's 749 square miles on soluble rock. With about 23,406 residents (31 per square mile), much of the land is open, and the mapped rock may sit far from where people actually live. The figures come from 334 map points about 1.5 miles apart, so a pocket smaller than that can be missed or overstated.
